Four row circular cone roller bearings widely used in medium and low speed rolling mill. This kind of bearings are compact in structure, within the scope of the limited space size, may withstand the bigger radial, axial impact load. In general
in bearing configuration without additional thrust bearing. The mean rolling roll shaft neck may be relatively short, and the roll bearing block can be used on both sides of the same structure. In order to be able to quickly replace roll, this
kind of bearing clearance fit in rolling roll shaft neck. Clearance fit disadvantage is that the inner ring under the condition of the load on its base sliding, usually cause hardness below the base of the bearing ring wear. To some extent,
in order to reduce the influence of clearance fit. Bearing which reduce wear and tear, inside hole has a spiral groove, or circle, side have a groove. These oil lubricant to the inner ring and the base contact surface.
